ST Regarding the last scene[Spoilers! Read at your own risk]

The look on Luke's face said it all...he looked at Rey, then at the saber and had a very displeased and shaming look about him. She had found and touched the saber, it activated/ awoke the force in her and he knew that his keeping her a secret was now at an end, and that she had been drug back into all of this. Somehow, her memories had been suppressed. She was hidden, cut off from the force, only to be found anyway. She had clearly received training in her past, back just before the mutiny of the Jedi. Anyone else in league with this thought? What was your interpretation?
